Abstract
The utility model relates to a pressure reducing device in an oil field, in particular to a ground pressure reducing device for an oil well. The technical scheme is as follows: the ground pressure reducing device mainly consists of an ejector, a water inlet pipe, a water inlet gate, a water connection gate, an oil inlet gate, an oil outlet gate, an oil linkage pipe, an exhaust valve, an oil collection pipeline, a one-way valve and a filter, wherein the ejector and the oil outlet gate are connected in turn through the oil collection pipeline, and the same side of the oil collection pipeline is connected with the oil inlet pipe through the oil linkage pipe and forms a loop with the oil collection pipeline; the oil inlet valve is arranged between the oil inlet pipe and the oil collection pipeline; the oil inlet pipe is connected with the water inlet pipe through the water linkage valve; the water inlet pipe is connected with the oil collection pipeline; and one end of the oil collection pipeline connected with the water inlet pipe is provided with the exhaust valve. The utility model has the beneficial effects of increasing the crude oil yield, reducing the load on the head of a pumping unit, the power use, the return pressure of the oil well and the power consumption of each ton of liquid, improving the yield of crude oil and realizing the aim of energy conservation and emission reduction, along with reasonable design.
Description
One, technical field:
The utility model relates to a kind of oil field dropping equipment, particularly a kind of oil well ground dropping equipment.
Two, background technology:
At present, the method that the way of heavy oil wells solution ground transportation problem routine generally adopts the ground water mixing to accompany, it is the water under high pressure with water filling main line 16MPa, directly mix the oil well surface line through the water nozzle expenditure and pressure, Oil Well Back Pressure is decreased, but the pressure of water under high pressure can be played a role, wasted the energy of water under high pressure, can not reach the purpose that reduces Oil Well Back Pressure.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of oil well ground dropping equipment is provided, and has reached the reduction Oil Well Back Pressure, improves crude output, reduces the consumption of electricity, has realized the order ground of energy-saving and emission-reduction.
Its technical scheme is: mainly be by ejector, water inlet pipe, inlet gate, water UNICOM gate, the oil-feed gate, fuel-displaced gate, the oil cross over pipe, vent valve, gathering line, ball-and-seat, strainer is formed, connect ejector successively by gathering line, fuel-displaced gate, the same side of gathering line is connected with oil inlet pipe by oily cross over pipe, form the loop with gathering line, be provided with the oil-feed gate between oil inlet pipe and the gathering line, oil inlet pipe connects water inlet pipe by water UNICOM gate, water inlet pipe links to each other with gathering line, and an end that connects the gathering line of water inlet pipe is provided with vent valve.
Above-mentioned water inlet pipe is provided with inlet gate and strainer.
Above-mentioned water inlet pipe is provided with inlet gate and strainer, is provided with ball-and-seat in the oily cross over pipe.
The beneficial effects of the utility model are: reasonable in design, improve crude output, and alleviate the load of oil pumper head, reduce power consumption, reduce Oil Well Back Pressure, improve crude output, reduce ton liquid power consumption, realized energy-saving and emission-reduction order ground.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: ejector 1, water inlet pipe 2, inlet gate 3, water UNICOM gate 4, oil-feed gate 5, fuel-displaced gate 6, oily cross over pipe 7, vent valve 8, gathering line 9, ball-and-seat 10, strainer 11, oil inlet pipe 12.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
The utility model mainly is by ejector 1, water inlet pipe 2, inlet gate 3, water UNICOM gate 4, oil-feed gate 5, fuel-displaced gate 6, oil cross over pipe 7, vent valve 8, gathering line 9, ball-and-seat 10, strainer 11, oil inlet pipe 12 is formed, connect ejector 1 successively by gathering line 9, fuel-displaced gate 6, the same side of gathering line 9 is connected with oil inlet pipe 12 by oily cross over pipe 7, form the loop with gathering line 9, be provided with oil-feed gate 5 between oil inlet pipe 12 and the gathering line 9, oil inlet pipe 12 connects water inlet pipe 2 by water UNICOM gate 4, water inlet pipe 2 links to each other with gathering line 9, and an end that connects the gathering line 9 of water inlet pipe 2 is provided with vent valve 8; Water inlet pipe 2 is provided with inlet gate 3 and strainer 11, is provided with ball-and-seat 10 in the oily cross over pipe 7; Wherein, ejector mainly is made up of big plug, adjustable water nozzle, trunnion, anemostat.
When device work, open fuel-displaced gate 6, oil-feed gate 5, slowly open inlet gate 3, this moment about 13MPa water under high pressure, after filter 11 filtrations, enter water nozzle ejection, under ejector 1 inner ventury effect, produce negative pressure, the crude oil in the oil inlet pipe 12 is sucked in the trunnion of ejector 1 by ejector 1, together its profit is mixed with the anemostat that water enters ejector 1, make pressure energy become kinetic energy, mixed liquor is entered in the gathering line 9, thereby the well mouth of oil well back pressure is descended, when if ejector 1 breaks down, crude oil in the pipeline will back down ball-and-seat 10 along oily cross over pipe 7 and enter oil inlet pipe 12, and the UNICOM's gate 4 of in time fetching boiling water is closed inlet gate 3, oil-feed gate 5, fuel-displaced gate 6, open vent valve 8 with gas emptying, can overhaul ejector.
